Abstract

A vacuum refrigerator for freezing and cold storage features that a vacuum pump and an air inlet valve are additionally used. Said vacuum pump is used to vacuumize the internal space of refrigerator, so the food can be stored in vacuum and sterilization state. Said air inlet valve is used before the door of refrigerator is opened. Its advantages include simple structure long storage period of food and high antistaling effect.

Description

Vacuum refrigerator, refrigerator

Vacuum refrigerator of the present invention, refrigerator belong to food carry out freezing, refrigeration, the insulation novel evacuated formula preservation device.

Refrigerator, refrigerator have become requisite freezing, refrigeration thermal protective aid such as family, restaurant, hotel in daily sphere of life at present.Though but existing refrigerator, the refrigerator that generally uses can make food preserve under different temperature, so that the storage article never degenerate or slow down rate of deterioration, but also exist unsurmountable shortcoming, as the food of storage in 3-4 ℃ refrigerating chamber, resembling its intracellular metabolism such as fruit, vegetables is still carrying out, only its speed slows down, still can produce putrid and deteriorated, so the time of preserving is also very limited.The food that is placed in addition in the refrigerating chamber can make its protein denaturation below 0 ℃, it is very obvious for example to resemble its protein denaturations such as bean curd, fish, meat, its mouthfeel is mutually far short of what is expected with fresh food when food consumption, at existing refrigerator, the existing problem of refrigerator, a kind of novel vacuum refrigerator with fresh-keeping function of Development and design, refrigerator are very necessary to overcome existing problem.

In view of above-mentioned existing in prior technology problem, purpose of the present invention is applied to the vacuum freshness retaining technology in refrigerator, the refrigerator, existing refrigerator, refrigerator is become have novel evacuated refrigerator, the refrigerator of fresh-keeping function.Thereby have the vacuum insulation performance good, save electric power, noise is low, the heat preserving antistaling degree is good, free from extraneous odour is ganged up mutually, food remains unchanged for a long period of time characteristics such as matter.Family, restaurant and hotel etc. be can be suitable for widely and need department and unit freezing, refrigeration be carried out food.

The invention provides a kind of vacuum refrigerator, refrigerator, its structure is made up of shell body, refrigerating chamber door refrigerating-chamber door, refrigerating chamber, refrigerating chamber, handle; In the shell body of refrigerating chamber and refrigerating chamber, be provided with vavuum pump and air bleeding valve, after refrigerating chamber door and refrigerating-chamber door are closed, vavuum pump is worked automatically, by air bleeding valve with indoor air all extract out form vacuum after, vavuum pump work stops, and when needs open cold chilling chamber door or refrigerating-chamber door, opens the intake valve that is contained on the catch, air is entered in refrigerating chamber or the refrigerating chamber, external pressure identical then open cold chilling chamber door or refrigerating-chamber door in causing.In the refrigerator and refrigerator that the present invention is applied to the vacuum freshness retaining technology now to have used, in the refrigerating box of former refrigerator (refrigerator) and household freezer, has the vacuum plant of making, when the cabinet door is closed the work of final vacuum device, after making the interior formation of cabinet vacuum state, make vacuum plant work and stop, forming vacuum freshness retaining state in the cabinet.

Vacuum refrigerator provided by the present invention, refrigerator are in the refrigerator and refrigerator that the vacuum freshness retaining technology is applied to now use, thereby make a kind of novel refrigerator, refrigerator that obtains significant improvement in being widely used in living.Adopt the present invention can make the food in the cabinet of packing into, the case be in vacuum, adiabatci condition, can make in fresh vegetables, the fruit cell tissue metabolism slowly or be tending towards stopping, thereby the freshness of maintenance food that can be long-term, and it is rotten to go bad.Again because food is in vacuum state, the smell of different types of food such as meat, fish, egg is remained in health and taint of odour mutually, so refrigerator, refrigerator use also free from extraneous odour for a long time, thus the expense and the trouble of saving taste removal.The pack if employing vacuum bag store food can be classified, effect is better, adopt in a word the present invention that food is in not only can to obtain that former refrigerator-freezer, refrigerator are freezing, the effect of refrigeration but also be in the state of sterile vacuum again, so belong to a kind of very desirable novel evacuated refrigerator, refrigerator.

Accompanying drawing of the present invention is the structural representation of vacuum refrigerator, refrigerator.

Among the figure: 1, shell body 2, door of refrigerator 3, cold sotrage door 4, refrigerating chamber 5, refrigerating chamber 6, handle 7, vavuum pump 8, air bleeding valve 9, intake valve 10, pressed switch

Specific embodiments of the invention as shown in drawings; A vavuum pump 7 is housed having freezing, the bifunctional refrigerator of refrigeration or the inboard of the shell body 1 in the refrigerator, makes vavuum pump 7 work or stop by pressed switch 10 control circuits.Vavuum pump 7 is connected with refrigerating chamber 4 and refrigerating chamber 5 by vacuum pipe.On the handle 6 of door of refrigerator 2 and cold sotrage door 3, have intake valve 9, when sliding door, can realize intake valve 9 air inlets, make indoor and outdoor pressure identical to reach the purpose of opening door.For the food of being placed in refrigerating chamber 4 or refrigerating chamber 5 can store classifiedly, at the indoor separation layer that is provided with.The shell body of refrigerator or refrigerator-freezer is the obturator of withstand voltage (＞1.5 atmospheric pressure) among the present invention, it is the support of spacer in installing that inner housing is arranged in the shell body, inner housing and shell body are apart from 0.5cm, fix by the insulation point-like between two bodies, inner housing is not airtight but open, makes the inside and outside pressure everywhere of shell body and inner housing all identical like this.

Claims

1, a kind of vacuum refrigerator, refrigerator are made up of shell body (1), refrigerating chamber door (2) refrigerating-chamber door (3), refrigerating chamber (4), refrigerating chamber (5), handle (6); In the refrigerator and refrigerator that it is characterized in that the vacuum freshness retaining technology is applied to now use, in the refrigerating box of former refrigerator (refrigerator) and household freezer, has the vacuum plant of making, when the cabinet door is closed the work of final vacuum device, after making the interior formation of cabinet vacuum state, make vacuum plant work and stop, forming vacuum freshness retaining state in the cabinet.
